Description

Technical Field

[0001] This invention relates to the field of cabbage decoction equipment technology, specifically to a dual-station rotary cabbage decoction machine. Background Technology

[0002] Before further processing, the hard core of cabbage needs to be removed. The food industry typically uses two methods for this: one is to employ a large number of workers to manually remove the core using drills. However, the cabbage core is hard, making removal laborious, risky, and inefficient, with high labor costs. The other method uses simpler decoction machinery. Commonly available decoction machines use a motor-driven conical drill bit. Workers hold the cabbage and press the core into the drill bit, removing it afterward. While this method is less strenuous than manual removal, the high-speed rotating drill bit has significant forward force, and improper pressing can easily puncture the cabbage, increasing the risk. After decoction, the cabbage still needs to be manually removed. For high-speed production lines, multiple machines need to operate simultaneously to meet the production line's needs, resulting in lower efficiency. Summary of the Invention

[0008] Preferably, the supporting mechanism includes a lower turntable and a plurality of circumferentially distributed claws. The lower turntable is rotatably mounted below the fixed plate. The lower turntable has circumferentially distributed sliding grooves adapted to the claws. The two ends of the sliding grooves are at different distances from the central axis of the protective cylinder. A lower roller is embedded in the sliding groove. The root of each claw is hinged to the inner wall of the protective cylinder via a hinge. One end of a lower connecting rod is rotatably mounted to the axis of the lower roller, and the other end of the lower connecting rod passes through the protective cylinder and is fixedly connected to the back of the claw. The lower turntable is powered by a lower cylinder.

[0010] Preferably, a power mechanism is installed below the rotating shaft of the indexing plate. The power mechanism includes a motor, a divider, a sprocket, a chain, and a chain. The rotating shaft of the motor is poweredly connected to the input shaft of the divider. The output shaft of the divider is equipped with the sprocket. The lower end of the rotating shaft of the indexing plate is equipped with the sprocket. The chain is installed on the sprocket and the chain.

[0011] Preferably, the core removal mechanism includes a cutter head, a cutter bar, and a rotary lifting mechanism.

[0014] The workbench of this invention is equipped with two workstations. The indexing plate rotates 180° at a time, with two clamping mechanisms corresponding to the two workstations. The clamping mechanism at the unloading workstation opens its jaws first, while the support mechanism's claws close. After the worker places the cabbage on the support claws, the jaws clamp. The indexing plate rotates 180° forward to transfer the cabbage to the de-coring workstation. The de-coring mechanism then rises to de-cor the cabbage. After de-coring, the indexing plate rotates 180° backward, and the de-cored cabbage returns to the unloading workstation. The jaws and support claws open simultaneously. The cabbage falls out of the discharge cylinder. During production, the two stations can operate simultaneously for every 180° rotation of the indexing plate. That is, for every 180° rotation of the indexing plate, the unloading station unloads de-cored cabbage and loads un-cored cabbage, while the de-coring station removes the cotyledons from the cabbage. In the process of the indexing plate reciprocating, the de-coring of cabbage is carried out in an automated manner, which greatly improves production efficiency. At the same time, workers only need to place the cabbage on the clamping and supporting mechanisms of the unloading station. The de-coring work does not require manual intervention and has a high degree of safety. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] This invention provides a dual-station rotary cabbage decoction machine, which breaks down the decoction process into two stations. The stations work in tandem to achieve fully automated cabbage decoction, improving efficiency and safety. The specific technical solution is as follows:

[0028] A dual-station rotary cabbage decoction machine includes a worktable 1, on which a material placement station 2 and a decoction station 3 are evenly distributed around the circumference. Material placement stations 2 and 3 each have a material discharge port. A dividing plate 4 is rotatably mounted on the worktable 1, with a surrounding plate 11 around its edge. Two sets of evenly distributed clamping mechanisms are mounted on the dividing plate 4, and a supporting mechanism is installed below the clamping mechanisms. The supporting mechanism supports the bottom of the cabbage stalk, and the clamping mechanism clamps the sides of the cabbage stalk. A decoction mechanism capable of vertical extension and retraction for removing the cabbage core is located below the decoction station 3, and a discharge cylinder 12 is located below the material placement station 2.

[0029] Furthermore, in this embodiment of the invention, two protective sleeves 5 are evenly distributed around the indexing plate 4. The positions of the protective sleeves 5 are adapted to the positions of the two workstations. A fixing plate 51 is fixedly installed on the outer wall of the protective sleeve 5. The clamping mechanism is installed on the upper part of the fixing plate 51, and the supporting mechanism is installed on the lower part of the fixing plate 51. The protective sleeves 5 and the fixing plate 51 serve as support components for installing the clamping mechanism and the supporting mechanism, facilitating installation and maintenance during use.

[0030] Specifically, the clamping mechanism includes an upper turntable 61 and four circumferentially distributed grippers 62. The upper turntable 61 is rotatably mounted above the fixed plate 51. Upper sliding grooves 63, adapted to the grippers 62, are evenly distributed circumferentially on the upper turntable 61. The two ends of the upper sliding grooves 63 are at different distances from the central axis of the protective cylinder 5. An upper roller 64 is embedded within the upper sliding groove 63. The root of each gripper 62 is hinged to the inner wall of the protective cylinder 5 via a hinge. One end of an upper connecting rod 65 is rotatably mounted to the shaft of the upper roller 64, and the other end of the upper connecting rod 65 passes through the protective cylinder 5 and is fixedly connected to the back of the gripper 62. The upper turntable 61 is powered by an upper cylinder 66. During the extension and retraction of the upper cylinder 66, the upper turntable 61 reciprocates around the central axis of the protective cylinder 5. As the upper turntable 61 rotates, the upper slide groove 63 rotates accordingly, enabling the upper roller 64 to move back and forth along the upper slide groove 63. Since the distance between the two ends of the upper slide groove 63 and the central axis of the protective cylinder 5 varies, the distance of the upper roller 64 from the outer wall of the protective cylinder 5 will also increase or decrease, thereby causing the upper connecting rod 65 to extend into the protective cylinder 5 at different lengths, thus enabling the upper connecting rod 65 to push the gripper 62 to clamp and release.

[0031] Specifically, an upper arc-shaped groove 67, concentric with the protective sleeve 5, is provided on the upper turntable 61. An upper roller 68 is embedded in the upper arc-shaped groove 67. One end of an upper straight rod 69 is hinged to the edge of the upper turntable 61, and the other end of the upper straight rod 69 is hinged to one end of an upper crank arm 610. The corner of the upper crank arm 610 is hinged to the indexing plate 4, and the other end of the upper crank arm 610 is hinged to the shaft end of the upper cylinder 66. The bottom of the upper cylinder 66 is hinged to the support plate 41 on the indexing plate 4. Directly hinged to the upper turntable 61 would occupy more space. Due to the limitations of the space structure, a crank arm + straight rod method is used for a roundabout hinge connection to achieve the opening and clamping action of the gripper 62 within a small space as much as possible.

[0032] Specifically, the supporting mechanism includes a lower turntable 71 and a plurality of circumferentially distributed claws 72. The lower turntable 71 is rotatably mounted below the fixed plate 51. A sliding groove 73, adapted to the claws 72, is circumferentially distributed on the lower turntable 71. The two ends of the sliding groove 73 are at different distances from the central axis of the protective cylinder 5. A lower roller 74 is embedded in the sliding groove 73. The root of the claw 72 is hinged to the inner wall of the protective cylinder 5 via a hinge. One end of the lower connecting rod 75 is rotatably mounted to the shaft of the lower roller 74, and the other end of the lower connecting rod 75 passes into the protective cylinder 5 and is fixedly connected to the back of the claw 72. The lower turntable 71 is poweredly connected to the lower cylinder 76. During the extension and retraction of the lower cylinder 76, the lower turntable 71 reciprocates around the central axis of the protective cylinder 5. As the lower turntable 71 rotates, the lower groove 73 rotates accordingly, causing the lower roller 74 to reciprocate along the lower groove 73. Since the distance between the two ends of the lower groove 73 and the central axis of the protective cylinder 5 varies, the distance of the lower roller 74 from the outer wall of the protective cylinder 5 will also increase or decrease, resulting in different lengths of the lower connecting rod 75 extending into the protective cylinder 5. This enables the lower connecting rod 75 to push the claw 72 to clamp and release. When clamping, the claw 72 supports the lower end of the cabbage stalk and provides height positioning for the root of the cabbage, ensuring that the core removal mechanism reaches the same depth during core removal.

[0033] Specifically, a lower arc-shaped groove 77, concentric with the protective sleeve 5, is provided on the lower turntable 71. A lower roller 78 is embedded in the lower arc-shaped groove 77. One end of a lower straight rod 79 is hinged to the edge of the lower turntable 71, and the other end of the lower straight rod 79 is hinged to one end of a lower crank arm 710. The corner of the lower crank arm 710 is hinged to the indexing plate 4, and the other end of the lower crank arm 710 is hinged to the shaft end of the lower cylinder 76. The bottom of the lower cylinder 76 is hinged to the support plate 41 on the indexing plate 4. Directly hinged to the shaft of the lower cylinder 76 and the lower turntable 71 would occupy more space. Due to the limitations of the space structure, a crank arm + straight rod method is used for a roundabout hinge connection to achieve the opening and clamping action of the claw 72 within a small space as much as possible.

[0034] Furthermore, in this embodiment of the invention, a power mechanism is installed below the rotating shaft of the indexing plate 4. The power mechanism includes a motor 81, a divider 82, a sprocket 83, a sprocket 84, and a chain. The rotating shaft of the motor 81 is poweredly connected to the input shaft of the divider 82. The output shaft of the divider 82 is fitted with the sprocket 83. The lower end of the rotating shaft of the indexing plate 4 is fitted with the sprocket 84. The chain is mounted on both the sprocket 83 and the sprocket 84. The function of the divider 82 is to precisely control the rotation angle of the indexing plate 4, thereby controlling the positional accuracy of the two clamping mechanisms rotating to the two workstations. Since the divider 82 is conventional prior art, its detailed structural principle will not be described in this invention. In this embodiment, the divider 82 is set to output a rotation angle of 90° for each revolution of the motor, and the diameter ratio of the two sprockets is D. 链轮一83 :D 链轮二84 =2:1. After calculation, it was successfully achieved that the indexing plate 4 rotates 180° for every revolution of the motor.

[0035] Furthermore, in this embodiment of the invention, the core removal mechanism includes a cutter head 91, a cutter bar 92, and a rotary lifting mechanism 93. The cutter head 91 is mounted on the upper end of the cutter bar 92, and the lower end of the cutter bar 92 is poweredly connected to the rotary lifting mechanism 93. The rotary lifting mechanism 93 is used to control the cutter bar 92 to rotate while vertically lifting.

[0036] Specifically, the rotary lifting mechanism 93 includes a mounting plate 931, a rotary motor 932, a belt pulley transmission mechanism 933, and a second cylinder 934. The cutter bar 92 is rotatably inserted into the mounting plate 931. The rotary motor 932 is rotatably connected to the cutter bar 92 through the belt pulley transmission mechanism 933. The second cylinder 934 is mounted on the mounting plate 931, and the end of the telescopic rod of the second cylinder 934 is connected to the lower end of the cutter bar 92 through a connecting plate 936. In order for the second cylinder 934 to extend and retract more smoothly vertically, four vertical sliding rods 935 are installed on the connecting plate 936. The rotation of the motor is transmitted to the cutter bar 92 through the belt pulley transmission mechanism 933. The rotation of the cutter bar 92 causes the cutter head 91 to rotate. At the same time, the vertical extension and retraction of the telescopic rod of the second cylinder 934 can drive the cutter bar 92 to extend and retract vertically, realizing the action of the cutter head 91 extending upward and retracting downward. In the rotary lifting mechanism 93, the radial rotation between the rod body of the cutter bar 92 and the belt pulley of the belt pulley transmission mechanism 933 is limited, while the vertical movement is not limited. Therefore, the belt pulley transmission mechanism 933 can still control the rotation of the cutter bar 92 during the vertical extension and retraction of the cutter bar 92.

[0037] The cutter head 91 includes a twisted drill bit 911 at the tip and a conical cutter disc 912 at the tail. When the twisted drill bit 911 drills into the cabbage core, it applies a downward pulling force to the cabbage, making it easier for the cutter head 91 to drill into the cabbage core and remove the core. To facilitate the collection of the removed cabbage core, a discharge hopper 10 is provided below the core removal station 3 to facilitate the discharge of waste.

[0038] The workbench 1 of this invention is equipped with two workstations. The indexing plate 4 rotates back and forth in a 180° manner, that is, the two clamping mechanisms are respectively located on the two workstations. The double-workstation cabbage rotary decoction machine decocts a cabbage in the following steps: (1) The clamping mechanism located at the material placement workstation 2 opens the clamping claw 62 first. At this time, the support claw 72 of the supporting mechanism closes. After the worker places the cabbage on the support claw 72, the clamping claw 62 clamps it; (2) The indexing plate 4 rotates forward 180° to transfer the cabbage to the decoction workstation 3. Then the decoction mechanism rises to decoct the cabbage; (3) After decoction is completed, the indexing plate 4 rotates backward 180°. The decoction cabbage returns to the material placement workstation 2. The clamping claw 62 and the support claw 72 open at the same time. The cabbage falls out and flows out from the discharge cylinder 5.

[0039] The above steps describe the decoction process for a cabbage on the entire machine. In reality, during production, both workstations can operate simultaneously for every 180° rotation of the indexing plate 4. That is, for every 180° rotation of the indexing plate 4, the material placement workstation 2 discharges decoction cabbages and loads uncorked cabbages, while the decoction workstation 3 completes the decoction of the cabbages. During the reciprocating rotation of the indexing plate 4, the decoction of cabbages is streamlined, greatly improving production efficiency. At the same time, workers only need to place the cabbages on the clamping and supporting mechanisms of the material placement workstation 2, and the decoction work does not require manual intervention, thus ensuring high safety.
